The following URL is the Microsoft DLL Help Database:

It shows that usp10.dll has shipped with: 98SE, Me, 2k & XP, and also with
IE 5.0, 5.5, and 6.0, and numerous Windows Installer redistributables.

This suggests that relying on usp10.dll (providing you have additional
version contraints) is a distinctly possible option. As to whether you need
fallback code or not, it depends on your attitude to people still running
95, 98 1st Edition & NT4.
